The soundman made a copy of his master soundboard cassette for me. My tape is a Maxell XLII-S 90, but the soundman's master was a cheap low bias tape recorded on a bottom of the line Sharp cassette deck (the house deck). Understandably, soundmen concentrate more on mixing sound for the house than on making good recordings, but of course I'm glad this recording was made and that I got to get a copy of it.
